You can try the splint method since he cannot move around to his legs without bending his body. You HAVE to wrap the leg where the bone is poking out. HAVE TO.
I suggest asking your vet for Chlorhexidine, an anti septic used post surgery. Use it twice a day and change the bandage at the same time; once in the morning once in the evening.
He also needs antibiotics, so ask for Baytril from the vet and follow the instructions on how much to give the poor baby.
The Chlorhexidine is condensed so you NEED to water it down - 1 part Chlorhexidine with 10 parts water THEN use. It's only good for 20 minutes before it becomes settled and stagnant so you need to make a new batch before every cleansing/bandage replacement.
I suggest making the smallest quantity possible using the 1 part 10 part method and using cu-tips to cleanse it. Dab gently and make sure to use a lot of the liquid (You are washing it, not wiping it so make sure the cu-tip is heavily soaked, and use a new cu-tip every time.)
Please baby him as much as possible and make sure he continues to be alert and let him rest where you can SEE him (Take all huts and houses and wheels away, so you can make sure he doesn't chew at himself. When he is doing better then you can return the housing and when he is completely healed return the wheel.) He is in "quarantine" until he heals. His cage needs to be turned into a medical cage, so replace bedding with soft tissue (no cotton), take the bowl away and just sprinkle the food in one spot so he doesn't have to work to get into the bowl, and lower the water bottle so he can reach it on all fours.
Please show me a photo of his injuries so I can assess the situation. Sometimes it's better to put them down and sometimes they can be salvaged if you are willing to put the work into it. Try everything you can first, as euthanasia should be the last resort.
